Abstract
A method and system for built-in self-testing for high-performance circuits, configured to generate and apply a test pattern to a circuit under test (CUT). A logic structure in communication with the CUT and a memory device generates a plurality of test seeds from a plurality of original test seeds, the generated test seeds and original test seeds defining a total test seed plurality and a subset deterministic test pattern plurality. A response suppression circuit suppresses test responses from the CUT if not generated responsive to a deterministic test seed of the deterministic test pattern plurality.
